The Fourth Industrial revolution
Digital design
BIM A process for creating and managing information on a construction project. One of the key outputs of this process is the Building Information Model, the digital description of every aspect of the built asset. – NBS, 2016
Digital House building- Why? Standardised process Improve visualisation Enhance collaboration Reduce waste Improve sustainability Resolve conflict Easier to manipulate changes as the project progresses Reduce planning cycle Improved quality
The shift from 2D to 3D Models
2D Dumb paper based drawings, schedules & specifications
3D “Intelligent” Digital Model, with embedded information
What is 3D? In 3 Dimensional drawings you work with the Zaxis, in addition to the X and Y axis Plan views, sections and elevations represent only two dimensions Any change applied to one view will be reflected in all views
Digital models and system libraries Digital data rich Component & System Libraries Digital House models
Geometry representing the product’s physical characteristics Digital Developed Designs

Initial steps KMT Issue: AutoCAD footprints that reflect Revit files Latest revision of 3D Revit house types PDF Packs ‘Core Working Drawings’ KMT Design guide Architects issue: AutoCAD files with site layouts Site Specific Working Packs and Link Block packs, created in Revit, issued in PDF format
Next steps… Digital Design & Place-making 3D Site creation Creating site layouts in Revit Architects to provide true site visuals (2D images, 360 images and interactive walkthroughs) at any stage of the project Federate the engineering and architectural outputs

ROI…… Where will it come from?
• Reduce planning cycle
• plot saving in abnormal costs through 3D land design
• increase in the likelihood of securing planning
• Reduction in site architectural design time
• increased support for community consultations
• productivity gain for technical users
• plot saving in defects and snagging • plot saving in marketing costs
• increase in handovers on time
• Increase in sales rates
• plot saving in cost of missed handovers & NHBC resolutions
• plot saving in development finance costs • Move towards a build to order business model
• plot saving in reworks and making good, due to early clash detection • improvement in safety performance
• increase in recommendations and referrals, retention of 5 * • Digital move in packs & aftercare • Higher likelihood of customers buying off plan • Brand differentiation due to visualization and potential personalization • Potential for early deposits, easing cash flow
The journey ahead
Speed of change is unprecedented and we need to be open to opportunities, challenge the traditions to find solutions that compliment our current ways of working to meet demands of the future. Modernise or Die – Farmer Review 2016
